Unclassified Planets are quite simply those that haven’t been explored yet, or their records have been lost. It has been said that during the Heresy, mankind’s fleets shot out in all directions. Most of these planets are known only because very little of them was scanned. Many of these can be potential gold mines of raw minerals, exotic materials, or even lost tech of the Golden Age of Man.
Unclassified Systems are noted on the map with a white system marker.
